page_title: Terminating Gateway - Configuration Entry Reference
|
|
description: >-
|
|
The terminating gateway configuration entry kind defines behavior to secure outgoing communication between the service mesh and non-mesh services. Use the reference guide to learn about `""terminating-gateway""` config entry parameters and connecting from your service mesh to external or non-mesh services registered with Consul.

# Terminating Gateway Configuration Entry
|
|
|
|
-> **v1.8.4+:** On Kubernetes, the `TerminatingGateway` custom resource is supported in Consul versions 1.8.4+.<br />
|
|
**v1.8.0+:** On other platforms, this config entry is supported in Consul versions 1.8.0+.
|
|
|
|
The `terminating-gateway` config entry kind (`TerminatingGateway` on Kubernetes) allows you to configure terminating gateways
|
|
to proxy traffic from services in the Consul service mesh to services registered with Consul that do not have a
|
|
[Connect service sidecar proxy](/docs/connect/proxies). The configuration is associated with the name of a gateway service
|
|
and will apply to all instances of the gateway with that name.
|
|
|
|
~> [Configuration entries](/docs/agent/config-entries) are global in scope. A configuration entry for a gateway name applies
|
|
across all federated Consul datacenters. If terminating gateways in different Consul datacenters need to route to different
|
|
sets of services within their datacenter then the terminating gateways **must** be registered with different names.
|
|
|
|
See [Terminating Gateway](/docs/connect/gateways/terminating-gateway) for more information.
|
|
|
|
## TLS Origination
|
|
|
|
By specifying a path to a [CA file](/docs/connect/config-entries/terminating-gateway#cafile) connections
|
|
from the terminating gateway will be encrypted using one-way TLS authentication. If a path to a
|
|
[client certificate](/docs/connect/config-entries/terminating-gateway#certfile)
|
|
and [private key](/docs/connect/config-entries/terminating-gateway#keyfile) are also specified connections
|
|
from the terminating gateway will be encrypted using mutual TLS authentication.
|
|
|
|
~> Setting the `SNI` field is strongly recommended when enabling TLS to a service. If this field is not set,
|
|
Consul will not attempt to verify the Subject Alternative Name fields in the service's certificate.
|
|
|
|
If none of these are provided, Consul will **only** encrypt connections to the gateway and not
|
|
from the gateway to the destination service.
|
|
|
|
## Wildcard service specification
|
|
|
|
Terminating gateways can optionally target all services within a Consul namespace by specifying a wildcard "\*"
|
|
as the service name. Configuration options set on the wildcard act as defaults that can be overridden
|
|
by options set on a specific service name.
|
|
|
|
Note that if the wildcard specifier is used, and some services in that namespace have a Connect sidecar proxy,
|
|
traffic from the mesh to those services will be evenly load-balanced between the gateway and their sidecars.
|
|
|
|

## ACLs
|
|
|
|
Configuration entries may be protected by [ACLs](/docs/security/acl).
|
|
|
|
Reading a `terminating-gateway` config entry requires `service:read` on the `Name`
|
|
field of the config entry.
|
|
|
|
Creating, updating, or deleting a `terminating-gateway` config entry requires
|
|
`operator:write`.
